Tube is tear-shaped. Bike is riding well! Flopped to fixed. Been riding it to work in Shinjuku, which at first was awful. I was using Yamate-dori, which is one of the biggest streets in Tokyo, and the whole thing is a torn-up mess. Nowhere to go without getting punished by the pavement.
But I found another route that cuts through a pretty nice neighborhood and up past Yoyogi Park, so it's all good!
The one challenge is that my wife's firm does a yearly ride-up-mount fuji (up to the fifth station, nothing too crazy) and I want to do it on this bike but the idea is pretty scary. No way am I in shape.
